Applications of structural equation modeling in psychological research.

This chapter presents a review of applications of structural equation modeling (SEM) published in psychological research journals in recent years. We focus first on the variety of research designs and substantive issues to which SEM can be applied productively. We then discuss a number of methodological problems and issues of concern that characterize some of this literature. Although it is clear that SEM is a powerful tool that is being used to great benefit in psychological research, it is also clear that the applied SEM literature is characterized by some chronic problems and that this literature can be considerably improved by greater attention to these issues.

Community psychology as a model for the new private practice of psychology.

The continuing increase in graduates from training programs in psychology when coupled with the decline of publicly supported mental health facilities or funds will lead more psychologists to offer services privately. At the same time, the private practice of psychology is changing, and a community psychology model may be useful in the development and offering of services. The community concepts of prevention, crisis intervention, and consultation can be related to family, work, and health in the development of some of the services that will become more prevalent in private practice.

Psychological performance models as indicators of the effects of hypnotic drugs on sleep.

A theoretical and practical scheme for the measurement of change in psychological performance is presented. An information processing paradigm is used as the basis for the model while personality, memory, motivational and experiential variables are shown to be amenable to control via the application of standard experimental methodologies. The model is realised in practical experimental terms in the use of measures of choice reaction time and critical flicker fusion threshold. The reliability and sensitivity of these parsimonious indices of performance change is illustrated in a brief review of the effects of benzodiazepine hypnotics on early morning performance.

Pronoun resolution and discourse models.

Psychological investigations of pronoun resolution have implicitly assumed that the processes involved automatically provide a unique referent for every pronoun. We challenge this assumption and propose a new framework for studying pronoun resolution. Drawing on advances in discourse representation and global memory modeling, this framework suggests that automatic processes may not always identify a unique referent for a pronoun. In 9 experiments, we demonstrate that, unlike noun anaphors, pronouns sometimes do not produce relative facilitation of their referents in comparison with nonreferents. We argue that research on pronoun resolution must consider the discourse contexts in which pronouns are likely to occur.

Predicting responses to self-management treatments for chronic pain: application of the pain stages of change model.

Psychological treatments emphasizing a self-management approach have become commonly accepted alternatives to medical interventions for chronic pain. Unfortunately, these approaches often fail to engage a significant portion of targeted individuals and are associated with high drop-out and relapse rates. Informed by the transtheoretical model of behavior change and the cognitive behavioral perspective on chronic pain, the Pain Stages of Change Questionnaire (PSOCQ) was developed to assess readiness to adopt a self-management approach to chronic pain. Initial studies supported the reliability and validity of four distinct scales, Precontemplation, Contemplation, Action and Maintenance. The current study was designed to assess the ability of the PSOCQ to predict self-management participation and outcome. The PSOCQ and several relevant outcome measures were assessed before and after self-management treatment by 109 chronic pain patients. Profile analysis revealed that treatment completers and non-completers differed significantly across the four PSOCQ scales. Post-hoc comparisons indicated that pretreatment PSOCQ Precontemplation and Contemplation scores discriminated these two groups. Separate analyses revealed that Action and Maintenance scores increased over the course of treatment, and that changes in the PSOCQ scales were associated with improved outcomes. These findings suggest that increased commitment to a self-management approach to chronic pain may serve as a mediator or moderator of successful treatment. This study supports the predictive validity and utility of the PSOCQ, as well as the relevance of the stages of change model to self-management of chronic pain.

A psychological cascade model for persisting voice problems in teachers.

In 76 teachers with persisting voice problems, the maintaining factors and coping strategies were examined. Physical, functional, psychological and socioeconomic factors were assessed. A parallel was drawn to a psychological cascade model designed for patients with chronic back pain. The majority of the patients were found to be in a deadlocked situation (phase 1 of the cascade model), for which the combination of externalization and unawareness of the situation is the main risk factor. Subjective rating of the voice problem was assessed by the Voice Handicap Index (VHI) and a visual analogue scale (VAS). Patients in phase 1 of the cascade model showed higher VHI and VAS scores compared with the other patients. For a high VHI score, the combination of socioeconomic factors and being in phase 1 was the most important risk factor. Socioeconomic factors were the most important risk factors for a high VAS score. We introduce the term 'chronicity', which means that the problems are maintained, the patient finds himself in a deadlocked situation, and is sliding down into a chronic disease. 'Chronicity' is essentially different from 'chronic', which refers only to the duration of the disease. We consider maintaining factors and (inadequate) coping factors, which consist of emotional/psychological, physical and socioeconomic aspects, as indicators for chronicity.

The theory of planned behavior: use and application in targeting agricultural safety and health interventions.

Traditional farm safety programs rely mostly on iterations of knowledge-based components, typically lack local input into identification of issues and concerns, and are difficult to evaluate. Psychological models have been looked at as tools to address these problems. The Theory of Planned Behavior (ToPB) is a psychological model that has been used to understand behavioral beliefs and to provide a framework for using those beliefs as intervention targets. The fundamental characteristics of ToPB are reviewed. Examples of specifically stated behavioral questions are provided from ToPB application in field settings. Pertinent findings from an example study on personal protective equipment use and beliefs are summarized to illustrate advantages and disadvantages of using ToPB. ToPB can provide information useful in targeting interventions aimed at locally identified safety and health concerns. The use of beliefs identified using ToPB as intervention targets can increase the use of personal protective equipment beyond levels used prior to the intervention. And, ToPB has shown multiple correlations of 0.28 (up to 0.35 in other examples not reported) between intentions and self-reported behaviors, indicating that other contributory factors are present and need to be studied.

What is a health expectation? Developing a pragmatic conceptual model from psychological theory.

INTRODUCTION: Examination of the existing literature in respect of health expectations revealed both ambiguity in relation to terminology, and relatively little work in respect of how abstract theories of expectancy in the psychological literature might be used in empirical research into the influence of expectations on attitudes and behaviours in the real world. This paper presents a conceptual model for the development of health expectations with specific reference to Alzheimer's disease. METHOD: Literature review, synthesis and conceptual model development, illustrated by the case of a person with newly diagnosed, early-stage Alzheimer's disease, and her caregiver. OUTCOME: Our model envisages the development of a health expectation as incorporating several longitudinal phases (precipitating phenomenon, prior understanding, cognitive processing, expectation formulation, outcome, post-outcome cognitive processing). CONCLUSION: Expectations are a highly important but still relatively poorly understood phenomenon in relation to the experience of health and health care. We suggest a pragmatic conceptual model designed to clarify the process of expectation development, in order to inform future research into the measurement of health expectations and to enhance our understanding of the influence of expectations on health behaviours and attitudes.

Truth or consequences: the validity of self-report data in health services research on addictions.

This paper examines factors that influence the veracity of verbal self-report data in health services research, using a cognitive social-psychological model of the data-gathering process as an organizing framework. It begins by briefly summarizing the consequences that can result from measurement error. Next, a cognitive social-psychological model of the question-answering process is presented. Common assumptions regarding the utility of specific assessment methods are evaluated with particular emphasis on the strengths and weaknesses of alternative data sources. The framework is then applied specifically to understanding the factors that may affect self-report measures in health services research relating to alcohol and other substance use. Overall, self-report procedures can provide useful estimates of consumption in clinical settings when conditions are designed to maximize response accuracy.

A model of psychological adaptation to migration and resettlement.

The purpose of this qualitative study was to investigate the implications of migration for emotional status over time. Analysis of interview data provided by 25 Polish immigrants, who resided in the United States ranging from 4 months to 39 years, allowed the construction of a model describing migrants' psychological adaptation. Loss and disruption, novelty, occupational adjustment, language accommodation, and subordination were described as predominant aspects of migration and resettlement. Psychological adaptation required the dual task of resolving grief over losses and disruption involved with leaving Poland and of mastering resettlement conditions associated with novelty, occupation, language, and subordination. The model provides assessment parameters and direction for intervening with migrants who are distressed. The model may also be generalized to other types of life change as well.

A network model for generating differential symmetry axes of shapes via receptive fields.

Some symmetries (e.g. bilateral, rotational, translational) only describe quite specialized shapes, but differential symmetry axes (e.g. Blum, J. Theoret. Biol. 38, 205-287, 1973; Brady and Asada, Int. J. Robotics Res. 3, 36-61, 1984) describe more general shapes. Such axes are of interest in part because they form the 'backbone' of generalized cylinder and other shape representations used in shape recognition (e.g. Marr, Vision, W. H. Freeman and Co., NY, 1982; Biederman, Psychol. Rev. 94, 115-147, 1987). However, despite the popularity of these representations as psychological models, algorithms from machine vision for computing them have strong limitations as psychological models. This paper presents two versions of a network model, one of which is more plausible as a psychological model because it derives symmetry axes from the activations of idealized visual receptive fields.

Determinants of beliefs about illness: a study of parents of children with diabetes, asthma, epilepsy, and no chronic illness.

Social psychological models of health care behaviour frequently take as their starting point perception of the illness. This paper seeks to examine factors that may influence these perceptions. Beliefs about the seriousness of eleven childhood illnesses are compared in four groups of parents. Significant differences were evident between the groups of parents depending upon their experiences with illness. For three conditions (diabetes, asthma and epilepsy) the lowest rating of seriousness was made by parents with a child with that condition. For parents of children with diabetes, having a relative with diabetes in good health was associated with a perception of the illness as significantly less serious than those with a relative in average or poor health, or those with no relatives with diabetes. These results are interpreted within an information processing model. Implications of the findings for social psychological models of health care behaviour are discussed.

Path model of psychological antecedents to pain experience: experimental and clinical findings.

OBJECTIVES: Two studies are described addressing how anxiety, fear of pain, and catastrophizing impact on pain experience. METHODS: In study 1, 66 undergraduates (34 men, 32 women) completed measures of state and trait anxiety, fear of pain, and catastrophizing prior to participating in a cold pressor procedure. In study 2, 60 undergraduates (30 men, 30 women) completed the same measures and participated in dental hygiene treatment and rated the pain they experienced during a scaling procedure (removing deposits from the tooth surface). RESULTS: In both studies, fear of pain and catastrophizing were significantly correlated with pain intensity ratings, and fear of pain and catastrophizing were correlated with each other. Trait anxiety was correlated with catastrophizing but not with fear of pain or pain. Path analyses revealed significant paths from trait anxiety to state anxiety, from trait anxiety to catastrophizing, and from catastrophizing to pain intensity ratings. DISCUSSION: The findings suggest that although fear of pain and catastrophizing are related constructs, catastrophizing provides unique predictive ability for pain ratings, while fear of pain does not. Clinical and theoretical implications of these findings are discussed.
